I was trying to install a latest version of ggbio and in trying to do so I may have changed the bioconductor version from stable to use useDevel() mode of installing. Which did not solve my problem as most of the dependencies of ggbio are either broken in the devel version or fail to install. I was wondering if I could revert back from devel mode to the original mode so that I can make the packages that were working before and not working now (like GenomicsRanges) work again.
